My invention relatesto the drillingv of oil wells by the so-ca-lledrotarysystem andrel-atesparticularlyl to a rotary machine.

, In the art it is-practice to drill a well by 3 use ofabit' attached tothe lower end of a drill pipe. This drill pipe extends upward throughthehole already drilled and through the floor of the derrick. Mounted onthe floor of the derrick isl` a. rot Io drives the drill pipe. Therotary `machine commonly usedi has al base andarotary table supportedthereby, thisI rotaryl table being driven by means ofv apinion attachedto a pinion shaft. rIAhe ordinaryy rotary machine base is made in twohalves which are secured together byl bolts;

a; pa-irvofl wooden skids which are secured to it by bolts. tableissubjected to severe strainsin deep well drillingy whichr causesthe twohalves of the base to worl` loose, this resulting in a distortion offthepartsan'dE in a breakage ofsome art; Y p It is'an objectof'thisinvention to provide arotary'machine'having a special design ofbase which will be more rigid and' will bek stronger than the basesrofthe ordinary rotary machines sovv that the rotary machine of mylinvention will be`V able to-endure the strains to which suchmachines areordinarilysub-jected whelra deep wellisfdrilled.

Other objects and advantages/of. tion will'- bey made evidenthereinafter.

Referring to Figs. 2 toj linclusive, 'thefrotary machine 12 has a base21 including the; important features of the invention. VAssillustratedbest in Figs: 2, Sandi 4V the 'base 211 has av horizontal plate 22.The?. horizontal.. plate 22 has a large openingl23 which is sur; roundedby a vertica'lfcylindrical wall24f;V A. horizontal wall 25provides anannularfledgev 26 on which a bearing'race 27; (Fig. 2') is sup' ported.-The bearingfrace 27 supports-conical rollerbearings 28,:whichroller-"bearings: 'in turny support an uppery The upper bearingrace V29yis pressed into;v an annular channel 31 ofa rotary table 32, theI rotarytable 32 being rotatably supported,

'Ihefrotary table 32y has a centralcylindri cal projection 34 whichextendsY downward inside the cylindrical wall 24". The` projection 34surrounds an opening 35 l formedA through theerotary table. TheV rotarytable 32is-held in the position shown infFig. 2 by means ofk a holddownring The; holddown ring` 37l is provided withflanges 38. which aresecured-'by bolts 39' to the-'base'2-1'.

The bolts 39 extend through openings' pro- C vided in flat faces 40y ofthe' base, over'which. faces the'fla'ngesBS extend. I Formed on therotary table-32 isa bevel gear 42 Vwhich is' engaged by Valpinion 43, bymeans of which the rotary table 322is revolved'. The plate 22 of thebasel 21 is provided with an opening'1`45 through Vwhich the lowerportion'offA the pinion43 extends;V The pinion 43' is attached' to thekinner end ofthe pinion shaft 46, which pinion shaft 46'is ro-` tatablysupportedf by a bearing assembly` 47.

tudinally thereof are pairs of outer and inner longitudinal ribs 55 and56. Y The pairs of ribs 55 and 56 extend downward from the plate 22.This is clearly shown in Figs. t and 5. The ends of the pairs of ribs 55and 56 are rounded as illustrated in the drawings,

and are closed by curved end plates 57 which an integral base structurehaving a horizonform a part of the base 2l and are integral with Vtheother parts thereof. The pairs ofA ribsv 55 and' 56 are attachedtogether and rigidied bywebs 58. This is clearly shown by dotted linesin Fig. 3. It should he'noted that the webs 58 are placedat intervalsalong the pairs of ribs. As shown best in Figs. 2, 4 and 5, sole plates61 are placedfagainstthe lower ends 62 of the pairs of ribs 55 and 56and are welded thereto as indicated' at 63. The sole plates 61- not=onlyprovide bearing 4faces for the pairs ofl ribs 55 and 56 but refinforcestrong. Y

As shown best in Figs. 3 and 5, cross webs 65and end webs 66 areextendedtransversely them greatly, making the-base very cross webs 65 and end-webs 66 are. formed integrally and extend downward from the plate 22.They are not extended down, however, as far Vas `are thegribs 55 and 56.

It should be noted that'the base 21Jis an integrall 'structure with theexception of the sole plates 61. TheV sole plates 61 are at-- tached tothe base, however, by autogenous welding and therefore may. beconsideredas integral. vThe p urpose of the" longitudinal ribs 55 and 56and the sole plates 61 is twofold; first, they serve as skids wherebythe rotary machine is supported; and second, a

very important function of these construe-VV tions is to make the base21 rigid.y The ribs 55 and 56'extend the entire length ofthe base 21andY quite fully reinforce'theplate 22. The ribs 55 and 56 are inthemselves reinforced by the cross webs 5,8.and also by the sole plates61. It will beissen that this results in a strong structure. Theplate22is further reinforced by the "cross webs 65 the end webs 66." Y

The rotary table of this invention is an innovation in the art of`drilling wells by the rotary system. As VVpointed out above the bases ofthe rotary table have been made in two parts and the skids have beenmade of woodand have been made a separate part.

A-much superior base is pro-vided by Inyin-Y Y vention. KYThe specialconstruction of theV base provides one which is much stronger than thatof theordinary rotary table and is capable of enduring all strains towhich aro tary machine is subjected during the usual deep well drillingoperations. The weight of the base is not any morethan that ofthe rotarymachine andlis not objectionable for that reason. In the ordinaryVconstruction of base it was necessary toma-ke it quitethick plate andserving as skids; ltached to the lower ends ofsaid longitudinal tudinalribs, said sole so that there would be no bending.
